Why is dangerous to remove the radiator cap of a car when the engine is still hot?
Hot water in the radiator is under pressure and can burn you.
Why is it dangerous to open a radiator cap while the engine is still hot?
Opening a radiator cap while the engine is still hot is dangerous because the pressurized coolant can erupt and cause severe burns or scalding. As the engine heats up, the pressure inside the cooling system increases significantly, and releasing that pressure suddenly can lead to a violent spray of hot coolant. Additionally, the sudden change in pressure can damage the radiator or other components. It's always best to allow the engine to cool down before attempting to open the radiator cap.
Why do engine coolant fan keeping running after engine is turn off on 1999 intrigue?
The engine coolant fan can keep running after the engine is turned off in any car because the temperature gauge is in the radiator. As long as the radiator is still hot, the fan will keep running until the temperature gauge says it has cooled enough.
Should there be pressure in the radiator after cooling down?
No, there should not be pressure in the radiator after cooling down. If there is still pressure, it could indicate a problem with the radiator cap or the cooling system, such as a leak or a failing pressure release valve.
Where is the thermostat located on a 1998 Subaru Forester?
a prior response has explained your ? located in fitting where lower radiator hose connects to bottom of engine. engine water temp should be cooled before draining. to access need to drop plastic shroud under front of engine/radiator, then drain radiator into container, facilitate by opening vent on left side of radiator (has Philips screw cross), and remove radiator cap. from under car remove 2 bolts that hold fitting at end of lower radiator hose where connects to engine (caution - still some juice here). bend out of way to access the thermostat that will be pressed/wedged in seat with rubber o-ring (still more juice here).
How can you stop the car from overheating?
cars use a mixture of water and antifreeze or ethylene glycol to help cool your cars engine this mixture is pumped though your cars engine from the radiator where it is cooled by the passing of wind though the "slats" into the engine by what is called a water pump the cooled liquid then cools the engine an engine can over heat many different the first and easiest way is that there is not enough of this mixture in the radiator the next way an engine can over heat if the fan behind the radiator (if electric) does not turn on while the engine is hot and not moving (at a stop light persay) the next way an engine can over heat is is the water pump is "broken" and not pumping this mixture into the engine there are still many more ways an engine can over heat i suggest you consult your local mechanic for more help
Where is the low pressure air conditioning port on a 1996 Montero?
FInd the high pressure inlet. The low pressure is on the engine side of the radiator about the same height. All you will see is the little cap with the L on it. I know where to look and still have a hard time seeing it.
Why does coolant overflow the expansion tank only after you turn the car off?
This might be the result of an increase in coolant temperature. Once the engine stops the coolant is no longer being circulated and cooled by the radiator but it is still picking up residual heat from the engine. Heated coolant expands and can sometimes overflow. You might also have a bubble of air in the system. Try bleeding it. Or maybe the check valve in the pressure cap is bad.
Why is there not any pressure in the cooling system?
== == No pressure means a leak (Internal or External) or a bad radiator cap. Try the radiator cap first as it is the easiest to replace. If pressure still fails to build, inspect your system carefully. Look for ANY evidence of moisture on engine components and try to find the leaking gasket. Also be aware that some gaskets can give way inside your engine releasing pressure/ antifreeze into your Combustion chambers and/ or oil reservoirs causing irreparable damage.
What does a radiator hose do?
carries water from and to the engine to the radiator for cooling, there are 2 and contain hot water when the engine is running and will still be hot and pressurerised for an hour after the motor is shut off.
Replaced fans radiator sensor rfw engine light still on?
If an engine light is still on after replacing a fan's radiator sensor in a RFW engine the coolant sensor should also be checked. If the coolant sensor is bad it will send an error code to the car's computer.
Why does your 1997 Chrysler LHS keep overheating?
i have replace the thermostat, checked the fans,filled with water and it is still overheating. Very often, the waterpump leaks and stops working only years after it was last replaced. Coolant is probably not flowing from the engine to the radiator to be cooled.
